start by adding a name to your codeproject account. i like to know who i speak to.

then look in the properties dialog over your propertySheet in the resource editor, and spot the minimize/maximize options...

I cant get the damn list box to change the ownerdraw property when i subclass it.
Part of the code :

    CWnd * wnd = NULL;
    while (wnd = FindWindowEx(this->m_hWnd,(wnd == NULL ? NULL : wnd->m_hWnd),"ListBox",NULL))
    {
        MyListBox * temp = new MyListBox();
        temp->SubclassWindow(wnd->m_hWnd);
        temp->ModifyStyle(0,LBS_OWNERDRAWFIXED);
        TempControlAdd((CWnd*)temp); //for cleanup later
        temp = NULL;
    }

Thanks for the Help.

Hi there,

I think the LBS_OWNERDRAW* styles can be set only upon creation of the listbox control.

Hi,

I created dll and trying to export a function which in turn calls InvokeHelper function,But my dll is created using win32 dynamic library it is not recognizing InvokeHelper,so i included the macros,

_AFX_NO_OCC_SUPPORT and AFX_CDECL.Now it is showing error as,

error C2061: syntax error : identifier 'CWnd'.What i have to do.Please help me... Cry | :((

I removed windows.h from stdafx.h and included afxwin.h in my header file.Now it is not recognizing the InvokeHelper and it's parameters.Giving error as

error C2065: 'InvokeHelper' : undeclared identifier
error C2065: 'DISPATCH_METHOD' : undeclared identifier
error C2065: 'VT_EMPTY' : undeclared identifier

What would be the problem...

How do you expect to use an OCC_SUPPORT method by using the _AFX_NO_OCC_SUPPORT macro to ommit
OCC support in the MFC code??

Get rid of that macro!

*EDIT* You probably shouldn't be messing with AFX_CDECL either unless you know what you're doing.

Look at the declaration for CWnd::InvokeHelper()...

#ifndef _AFX_NO_OCC_SUPPORT
// OLE control wrapper functions
   COleControlSite* GetOleControlSite(UINT idControl) const;
      void AFX_CDECL InvokeHelper(DISPID dwDispID, WORD wFlags,
...

See why it won't work with that macro? Smile | :)

Its declared in afxpriv.h. But why you needed to use this class ?

Off the top of my head the answer would be YES! A template is just an outline of the code which the compiler needs to generate. That means that without the outline it can not generate it. Therefore it does not exist and can not exist until you provide the outline for it.

Bottom line: Include the header for any template that you wish to use.

Hi,

In my application there is two window.
I have used PreTranslateMessage

In that i have written

bool nFlag = CDialog::PreTranslateMessage(pMsg);

if(pMsg->message==WM_KEYDOWN)
{
if(IsCTRLpressed() && IsALTpressed())
{
if(IsDpressed())
{
//delete code
}
}
}

It is wroking on 2000 pro. but in XP
it's not wroking can any one tell me WHY?
what is wrong with it?

Thanks,
Rushiraj

IsCTRLpressed() looks like

#define IsCTRLpressed() ( (GetKeyState(VK_CONTROL) & (1 << (sizeof(SHORT)*8-1))) != 0 )

#define IsALTpressed() ( (GetKeyState(VK_MENU) & (1 << (sizeof(SHORT)*8-1))) != 0 )

#define IsDpressed() ( (GetKeyState('D') & (1 << (sizeof(SHORT)*8-1))) != 0 )

and when I press CTRK+ALT+D I want to execute delete function.

now when I press CTRK+ALT+D

IsCTRLpressed returns true
IsALTpressedreturns true

but
IsDpressed returns false

bool nFlag = CDialog::PreTranslateMessage(pMsg);

if(pMsg->message==WM_KEYDOWN)
{
if(IsCTRLpressed() && IsALTpressed())
{
if(IsDpressed())
{
delete();
//delete code
}
}
}

Thanks,

No need for this complex definition, simply

#define IsCtrlDown() ((GetKeyState(VK_CONTROL)<0)?TRUE:FALSE)

this will do.

rushiraj.jhala wrote:

IsDpressed returns false

You are handling the WM_KEYDOWN in PreTranslateMessage, so no need for IsDPressed, check

pMsg->wparam == 'D'

This will work in all the versions

-- modified at 3:09 Friday 23rd March, 2007
Also you can change the definition global to all keys as below,

#define IsKeyDown(nKeyCode) ((GetKeyState(nKeyCode) < 0)?TRUE:FALSE))

and you can call this as,

IsKeyDown(VK_CONTROL);
IsKeyDown(VK_MENU);

hi,
Thanks

But it is also not wroking,
I get
pMsg->wParam = 18.
